Measury conductivity standard
WebConductivity measurements cover a wide range of solution conductivity from pure water at less than 1x10-7 S/cm to values of greater than 1 S/cm for concentrated solutions. In general, the measurement of conductivity is a rapid and inexpensive way of determining the ionic strength of a solution. However, it is a non- WebFor conductivity systems that cannot have the resistance-measuring circuit disconnected from the electrodes (e.g., measurement circuit and electrodes in one mutual housing), it …
